What is a Sexist? by Jonny Anomaly and Brian Boutwell.
What kinds of statements about men and women constitute sexism? Is it sexist to say, for example, that on average, men are taller than women or that women live longer than men? Most people already accept the obvious truth that men and women differ in these physiological respects, and it would strain credulity to argue that such statements are blatantly sexist. Suggestions about psychological differences, however, can stoke controversy.
Pressing the issue further by claiming that psychological and cognitive differences might partly explain wage gaps, employment gaps, and the like, will certainly invite harsh rebuke and likely a charge of sexism. Like “racist”, the definition of “sexist” seems to have ballooned in such a way as to include any claim about average differences between males and females from the neck up. Some feminists, in particular, fear that assertions about differences between men and women threaten the social progress we’ve made over the past few centuries. Perhaps they have a point (as we discuss below). But we should consider whether such an expansive definition of sexism is helpful, or whether it actually represents a hindrance to moral progress.
